FerroFinestra W75 TB


The slim lines of the new W75 TB range and its visible and tactile surface structures have a strong emotional impact on the observer. Structures play an important role in window design, expressing the natural beauty of these materials and interacting with light in a unique way. Although both quality features are simultaneously visible to the human eye, the former is a haptic experience, while the latter evokes visual associations. The French novelist Antoine de Saint-Exupéry says in his description of perfection: “Perfection is achieved not when there is nothing more to add, but when there is nothing left to take away”. We took it at its word and W75 TB is the result.

The new FerroFinestra W75 TB system, which will be presented to the public for the first time at Bau 2019 in Munich, is the latest development from Ottostumm. Like the entire FerroFinestra range, the design recalls the simple, rational and sober lines of early 20th century European architecture. The system, consisting of 25 profile geometries, represents the most technologically advanced thermally insulated steel window system in our portfolio.

The profile depth of 75 mm allows to accommodate highly energy-efficient insulating glazing up to 52 mm and the fiberglass-reinforced polyamide insulator guarantees excellent thermal insulation, making the system ideal for projects in climatically demanding regions, where energy-saving regulations are extremely high. In addition to continuous galvanizing, we offer versions in steel, cor-ten steel and stainless steel (1.4404). The system is supplemented by a wide range of exclusive fittings and accessories reproduced from original designs of the modern era. It allows the realization of all common opening types (inside and outside opening) for both windows and doors, including tilt & turn opening mechanism. The system is available both flush and overlapping.
